Where is the chip, damnit!?

Alex has found a memory card in Crofton Park, that may or may not contain encrypted information that could prevent a terrorist attack and wants BC's help to find its owner:

I just found a 16GB Sandisk SDHC memory card on the pavement near the Brockley Jack on Stondon Park. It seems to contain lots of holiday photos from various places, taken with a Canon digital camera.

If that's your card, please email us and we'll put you in touch within 24 hours.
